    Brake Master cylinder

    Either of those will do. Just measure the thickness of the bolt flanges. If the new ones are thicker it will require a longer push rod. If thinner you’ll need a shorter push rod. Emery Stora > > Just installed a dorman one last week in a gmc. Fit perfectly and the casting was NOT too thick...

    Brake fluids -Dot 5?

    Yes, 5.1 is completely compatible with your existing fluid. Suck the brake fluid from th master cylinder and fill with Dot 5.1. Open the right rear bleeder. You can see if it will gravity bleed. Be sure to use a clear tube from the bleeder to the collection bottle so you can see air bubbles...

    Brake fluid - Dot 5?

    NO. Dot5 is a silicone based fluid. Do not try to convert to it. You can however convert to DOT 5.1. You should convert to it. convert it. I did a seminar at the Tallahassee convention last year about brake fluids and 5.1. It is probably on the GMCMI web site. 5.1 is a glycol based brake fluid...

    Converting freon

    Yes. Duracool is about 10% more efficient than R-12. R-134a is about 10% less efficient than R-12. I have been using Duracool for over 10 years. You don’t have to drain or flush any components. It is good to put in a new receiver/drier. That is also a filter and your old one might be partially...

    Original oven door

    I don’t have an oven like that anymore. Replaced with a microwave and top burners. If I recall the door had an inner panel and an outer panel with a stainless channel around the outside. There must be screws holding it together. You might have to take the dot off to get it apart. Emery > >...

    electrical connection

    You should be able to squeeze the connector to make a tighter fit. Don’t use regular pliers or you’ll probably make it too tight. I use small vice grips and possibly do a trial fit and if it’s not tight enough tighten them a little and try again. Also put some dielectric grease for better...

    GM Coils

    A friend asked me if I knew anyone that was familiar with GM Ignition Coils (Not HEI) He indicated that he has seen coils stamped on the metal outside with the numbers 135, 151, 200, and 221. Do these numbers have any meaning or are they just manufacturing lot numbers? Are they any...

    Cleaning gas tanks

    Carl Not Jim here but I don’t think any air to the tanks goes through the charcoal canisters. The carburetor (or tbi system) puts a vacuum on the canisters and pulls air through them to recover the fuel vapors that flow from the fuel tanks. No air flows to the tanks. The fuel cap is vented so...
